Delayed Menstruation: Causes and Concerns for Women - Obstetrics and Gynecology

Delayed menstruation can be a source of concern for many women, especially when it deviates from their regular cycle. In your case, with a typical menstrual cycle of 29 to 32 days and a delay of five days, there are several factors to consider that could explain this change.

First and foremost, illness can significantly impact your menstrual cycle. You mentioned experiencing a fever due to a viral infection (likely the flu) around the time your period was expected. Illness can lead to hormonal fluctuations, which may disrupt the normal regulation of your menstrual cycle. Stress on the body, whether from physical illness, emotional stress, or significant lifestyle changes, can lead to delayed ovulation or even anovulation (the absence of ovulation), which in turn can delay menstruation.

In addition to illness, other common factors that can cause delayed menstruation include:
1. Stress: Emotional or psychological stress can affect the hypothalamus, the part of the brain that regulates hormones responsible for menstruation. High levels of stress can lead to irregular cycles or missed periods.

2. Weight Changes: Significant weight loss or gain can also impact your menstrual cycle. Low body weight, particularly in athletes or those with eating disorders, can lead to missed periods due to hormonal imbalances.

3. Hormonal Imbalances: Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can lead to irregular menstrual cycles. If you have a history of hormonal issues, this could be a factor.

4. Medications: Certain medications, including hormonal contraceptives, can affect your menstrual cycle. If you have recently started or stopped any medications, this could also be a contributing factor.

5. Pregnancy: Although you mentioned using a condom and are confident there was no leakage, it’s always prudent to consider the possibility of pregnancy, especially if your cycle is irregular. If your period does not arrive soon, consider taking a home pregnancy test for peace of mind.

Given that your last period was on January 29 and you had sexual intercourse on February 5, the timing of ovulation and the lifespan of sperm (which can survive in the female reproductive tract for up to five days) could also play a role in your concerns. However, since you used protection, the likelihood of pregnancy is low.

If your period does not arrive within a week or if you experience other concerning symptoms (such as severe pain, heavy bleeding, or unusual discharge), it would be advisable to consult a healthcare provider. They can perform necessary evaluations, including blood tests to check hormone levels, and provide guidance based on your specific situation.

In summary, while a five-day delay in menstruation can be concerning, it is often not uncommon, especially in the context of recent illness and stress. Monitoring your symptoms and considering a pregnancy test if your period does not arrive soon are prudent steps. If you have ongoing concerns or if your cycle does not normalize, seeking medical advice is always a good course of action.
